The above is a wonderfully resonant quote from a model railway forum post.
It refers to the fact that the builder had made an assumption about a feature on his chosen prototype, but when he got around to checking up at his local club’s library, he found he needed to make some corrections. (This is a very minor example of the disruption caused by COVID-19, as he didn’t want to put the project on hold pending all the information.) Not everyone would have bothered, but that, perhaps, is the most succinct and compelling difference between a genuine “finescale” model-maker and someone who doesn’t want to get it right. I might add that wanting to find out these details is also a key part of the finescale approach.
There is also the point that pending full knowledge of prototype practice, a reasonable interpolation of the design was made – no hanging around waiting to “know everything”, just an acceptance that a correction would be made if necessary later. This applies to most things within our hobby, although once the track is laid, it can be difficult to change certain fundamentals of its design and construction without wholesale destruction!
